Backspace button in edit mode keeps navigating

Try accessing your WordPress site from a different computer see if the issue is specific to your environment.

Also, check if there are any keyboard shortcut conflicts with the Backspace key. Some browser extensions or operating system settings may override default shortcuts.

Thank you, I didn’t even think of extensions ??. I use https://chromewebstore.google.com/detail/go-back-with-backspace/eekailopagacbcdloonjhbiecobagjci which is why when I switched to my laptop I had the same issue. Whitelisting my WordPress install in its config solved my issues.
